The instant invention relates to a fresh water loading and waste waterdisposal system for house trailers, mobile residences, busses and thelike.

One of the primary objects of the invention is the construction of afresh water loading and waste water disposal unit for trailers, bussesand similar vehicles which may be readily connected to sources of freshwater and waste water disposal, such as the plumbing system of agasoline filling station or other available water supply.

Yet another aim is the incorporation of a fresh water loading and wasteWater disposal unit in a mobile residence, bus or trailer embodying areel and portable case, the reel having wound thereon a pair of flexiblehoses leading to a fresh water tank and a waste water tank,respectively, the terminal portions of the hoses being contained withinsaid case for connection, respectively, to a source of fresh water suchas a spigot or hydrant, and a waste water outlet such as a toilet bowl.

Yet another purpose is the construction of a fresh water supply andwaste water disposal system which is composed of relatively few partsand which embodies electrical means associated with a portable case forready operation of the waste water unloading and fresh water loading ofthe system.

The above and other aims and objects will be apparent from the detaileddescription hereinafter appearing when taken in conjunction with theappended drawings forming a part hereof to which attention is nowdirected and in which Fig. 1 is a diagrammatic view, partly inelevation, showing fresh water and waste water tanks in a portion of amobile residence, trailer or the like, as well as a hose-carrying reeland associated portable case and electrical means operatively connectedwith the tanks and reel.

In recent years house trailers and mobile residences have become verypopular and are to be found in increasing numbers on the highways and inso-called trailer camps or parks. One of the outstanding problemsattendant in the use of such mobile residences, trailers and the like isan eflicient system for disposal of waste water from and the loading offresh water on the trailer for use in the plumbing system thereof. Thein stant invention is directed to an efficient unit to be used at agasoline filling'station or any other place where a sewer outlet and afresh water spigot are available. This will be apparent from thefollowing detailed description. I

Referring now to the drawings, the reference character T designates aportion of a mobile residence, trailer or the like having a side wall 10and a bottom wall or floor II. The wall I 0 has an opening l2 thereinadapted to be closed by a door I 3 hinged as at M to the floor II. Afresh water tank l5 and a waste water tank are disposed within thetrailer T and as shown the waste Water tank l6 has a waste water inletpipe ll, an outlet pipe I8 leading from the bottom thereof and a vent [9adapted to pass'through the roof of the trailer. Similarly, the freshwater tank [5 has an inlet pipe connected adjacent the top thereof, anoutlet pipe 2 I, and a vent 22 similar to the vent l9. It will beunderstood that the pipe I! is connected to the waste Water portion ofthe plumbing system of the trailer, while the pipe 2| leads to the watersupply of the trailer and is connected to its spigots, shower, toiletand the like. Outlet pipe I8 terminates in a rotary coupling 25 fastenedto one side of a hose reel 26. A flexible hose 2! is operativelyconnected to the coupling 25 whereby waste water from the pipe 18 willflow through rotary coupling 25 and into hose 2'! in any position of thereel 26. In like manner, water inlet pipe 20 terminates in a. rotarycoupling 28 fastened to the other side of the hose reel 26, the coupling28 being connected to a second flexible hose 29 whereby fresh water fromthe hose 29 will flow through the rotary coupling 28 to the pipe 20 andinto the fresh water tank IS in any position of the reel 26.

Turning now to Fig. 1, it will be noted that an elongated portable caseC is shown in dotted lines resting on the floor I l of the traileradjacent the opening I2, the latter being adapted to be closed by hingeddoor [3 as previously described. The terminal portions of hoses 21 and29 are positioned within portable case C as will be best seen byreference to Fig. 4 of the drawings. The case C comprises a base portion30 and a hinged lid 3| having a carrying handle 3 l Lid 3| has a watermeter 32 mounted fixedly therein to one end of which flexible hose 29 iscoupled. A flexible hose portion 29 having an enlarged inlet head 29 iscoupled to the inlet end of water meter 32. It will now be understoodthat upon removal of hose section 29 and attachment of head 29 to awater spigot, water will? flow through hose section 29?, meter 32; hose29, pipe into the fresh water tank, as will be pointed out in moredetail hereinafter. Flexible hose 2'! terminates in an enlargedplunger-like cup or head 33..

Attention is now directed to Figshl and 5; and particularly to thelatter showing the pump mechanism mounted within the waste water outletpipe l8. This mechanism comprises-an electrical motor 34 which drivesa.motor shaft 35.

passing through the wall of the pipe i8, said shaft 35 having a crank 36fixedly secured thereto. Pivotally secured to the crank 36 as at 3]. isan. arm 38,. the. otherend of; the. arm 38 being pivotally attached.tothe: wrist. pim 36 of; a pump. pistonMl. The latter h-asabottom wall;or head. 4l apertured. as. at- 42,. said aperture beingcl'osedby aspring valve: 43.v Whenthe-n1ot0113-4 is energized. the crank. 36-isrotated. serving to. raise, the. pump. piston 49 and the, spring;valveis. then. opened permitting waste water to flow through aperture.42; Upon downward move.- mentlof thepumppiston 4il,the valve 43:010sesthe. aperture. 42 and water. is. forcedfromthe pipe [-8 in the directionofthe arrow of 5. It willnow be understood that-upon. operation. of. thepump water will flow through pipe [8, hose 21:, terminal head.33,the1atter being shown inFig. 3-as-p0siti'oned within a. waste. disposalopening of atoilet bowl; B.
